The Jeep Wrangler JK is a fine platform to both go wheeling, and, to build an awesome wheeler.
The frame is far beefier, than a TJ frame (which is also better than the YJ, CJ, etc). The body, is more durable than the TJ body (which is also better than the YJ, CJ, etc).
The downsides, are it's a heavier rig. A fully built JK 4 door, with armor, axles, winch is easily 6000 pounds, and sometimes even more. Plus, the 4 door is BIG. Like, really big. But, in a LOT of areas, that wheelbase and width is an advantage. However, on our trails, it's a PITA. But, for Tahuya, you'll be fine.
The engines are anemic. But there's lot of support, turbos, superchargers, and engine swaps. The axles are amazingly strong, for a stock axle, but are undersized for large tire upgrades on a heavy rig.
Also, from what I've seen and read, adding a traditional full roll cage is a PITA. The front dash area is harder to integrate. Although Mel at Evo Engineering has a kit now.
